Abstract

The existing four-stroke engine discharges high-temperature and high-pressure waste gas after doing work, so that part of energy is not utilized, and especially when heavy load is carried out, the energy lost by the discharged high-temperature and high-pressure waste gas is more. The invention relates to a secondary pneumatic component driven by waste gas and connected with an engine crankshaft, which drives the secondary pneumatic component when the waste gas is exhausted, so that the exhaust stroke of an engine works again. The device is equivalent to indirectly increasing the working stroke, can perform multi-level gradient working, is additionally provided with a boiling device, and improves the efficiency and the performance of the engine.

Description

Method for doing work again by engine exhaust

Technical Field

The invention relates to a method for a four-stroke engine to do work again in an exhaust stroke.

Background

The existing four-stroke engine discharges high-temperature and high-pressure waste gas after doing work, so that part of energy is not utilized, and especially when heavy load is carried out, the energy lost by the discharged high-temperature and high-pressure waste gas is more. The invention relates to a secondary pneumatic component driven by waste gas and connected with an engine crankshaft, so that the waste gas enters the secondary pneumatic component when being discharged, the exhaust stroke of the engine is enabled to do work again, and the efficiency of the engine is improved.

Disclosure of Invention

The invention relates to a secondary pneumatic component driven by waste gas, which is connected with an engine crankshaft, so that the waste gas drives the secondary pneumatic component when being discharged, and the exhaust stroke of an engine can do work again. The principle is that the rate of the volume reduction of the engine cylinder body is smaller than the rate of the volume increase of the secondary pneumatic assembly during the exhaust stroke, and the total volume of the engine cylinder body and the secondary pneumatic assembly is a process of increasing during the exhaust acting, so that the exhaust acting is realized. Which is equivalent to an indirect increase in the power stroke. Can multistage increase pneumatic assembly, can install check valve and relief valve additional and improve the reliability, can install outside air supply coupling assembling additional and install boiling device additional, improve the performance.

Drawings

Fig. 1 is a schematic diagram of the engine block 1, the secondary pneumatic assembly 2, and the exhaust duct 3 of fig. 1. Fig. 2 is a functional introduction diagram, in fig. 2, 1 motor, 2 transmission mechanism, 3 connecting pipe, 4 secondary exhaust pipe.

Detailed Description

As shown in fig. 1, the volume of the secondary pneumatic assembly 2 is larger than that of the engine cylinder 1, when the engine is in an exhaust stroke, the piston moves upwards, the piston in the secondary pneumatic assembly 2 moves downwards, the exhaust gas enters the secondary pneumatic assembly 2 through the exhaust pipeline 3, the rate of the volume reduction of the engine cylinder 1 is smaller than the rate of the volume increase of the secondary pneumatic assembly 2, and the movement at the moment is the process of the total volume increase, so the exhaust gas exhausted by the engine can continuously do work. This method is equivalent to an indirect increase in the stroke of the engine block.

As shown in fig. 2, the engine is connected with the motor 1 through the transmission mechanism 2, and the design should ensure that the total volume is increased in the exhaust stroke state of the engine. Can install outside air supply coupling assembling and pressure relief device in the connecting tube 3 additional and the check valve in addition, for example the exhaust heating makes water boil, and high pressure steam squeezes into connecting tube 3, and relief valve and check valve can improve holistic reliability. The secondary exhaust line 4 can be used for connecting the next exhaust gas-driven device, so that a gradient utilization of the exhaust gas is achieved.

The invention can be designed as a secondary cylinder coaxial with the crankshaft as shown in fig. 1. As shown in fig. 2, it is also possible to design the pneumatic components of different shafts to be matched by means of the gear mechanism 2.

Claims
